collapsing of the AUGUSTUS G. BoxELL, or

L0? ANGELES, CALIFORNIA FEM-TREATMENT CAGE.

Application filed July 19,

To all ichom it may concern Be it known that l, AUGUSTUS G. BOXELL,

a citizen of the United States, residing at Los Angers, in the county ofLos Angeles and State of California, have invented a new 'and useulFilm-Treatment Cage, of

which the following is a specification.

1 This invention pertains to means for suitably supporting: exposedfilms while they are being .Tere!;,pcd, fixed, WaShed'and'dried, and anobject of, the invention is'toj'pr'oi this character in which theTilmscan be placed and in which they can remain during the variousoperations incident to the converting of the eiposed v for printing.Shcet films are rapidly coming into genglass plates in conheretoforeemploying have heretofore been proholding su'ehfilms during theperformance of;the various processes whereby they a re convertedfromexposed condition to negatives ready for printlng.

Another-object is to construct a device of .this character in which aplurality offilms can he quickly. placed for various treatments and fromwhich saidfilms canbe 30 quickly removed.

I Another object is to provide adevice of this character comprisingseparate frames on which the films can be mounted, and a which theframes can beassembled thus making Another object is to make provisionfor rack, so that when not in use it can be folded into a comparativelysmall compass.

Other objects and advantages will appear in the subjoined detaileddescriptions;

The handles 34 may be .providedwith hooks 36, if desired, so that the rack can be hung on it li'ne,either in open position with the frames in place therein, or in foldedposition with the frames removed.

To fold the rack, all that is necessary is to detzfch the upper ends ofthe braces 26 and buckle upwardly the upper and lower side members andintermediate lower member at their joints and ush the ends of the racktoward one ah'o 'e'r, whereupon the 'b'iirces 26 "at each side 'willfold alongside of "ea-ch other land the upper and lower side sections 11, 14, 1'9, 20 "at each side will fold alon s'idefo'f 'eich other andthe sections 29, 20 wi'l'l fold aicmgside of each other. Reyer'sin'gthese operations will open the rank for use. L I

To use the invention, the films, after they lh'ifie beenekpe'sea' in acamera or canzieriis usealbeths er treatments to w'hitih the films tire'to he sfibgleeted, to wit, develo in fi'xing. 11 "single tank ma *beused for all of the treatments or processes 'or the 'rack may beinserted in different in; l, one tank for each treatment.

her th film's hsivebee'n treated b the w lds bfa'tlr's as aboveoutlined, the rack will be lifted from the tank by the handle in and'the rack win then beset on a :table or other suitable s'ueiiaeeto'ei'init'th'efilms, 110w negatives, todij In t 1e 'dryi'n Operatio'n'apower'driven fa'n may be (any eyed-to goon purpose, atidit isto be notedthat "the drying b the use of the pdwrd'ri'ven fa'n may be e' ems veryconvenientl with this invention, *s'in'e 'th'e rec'k e'aln bechanged inposition from time to time so its to hpply the current of air first toone edge-of the ilegati'ves'efldt'hen to'thebpposite'edge,'thus changingthe direction of the air current through the iadk and consequentlyminiinizing the time required for the drying o eration.

idr'n the'fo're 'oing it is clearthait th'e'films need not be touc edduring any of the crevicinents to which they "sire'sdbjectedaft'erexosure until ready for the printer sfn'dthat thusth'e'total timerequired for the various treatments is minimized asis alsotheda'hger ofscratching or otherwise injuring the films.

In this connection, it is to be noted, that, after the negatives havebeen dried in the frames, they may be left in said frames during anyretouching operation that may be desirable to perform on the negatives,the retoucher simply laying the frame, after removal from the rack, withthe negative attached thereto upon the retouching stand. The retouchercan turn the negative to-different positions without it being necessaryfor him to handle the negative,

The invention is not limited to the exact details of construction shownin the drawings and described above, but the invention also includessuch changes and modifications as lie within the spirit and scope of theappended claims.

I claim:

1. A film-treatment cage comprising uprights, notched upper memberssupported by the uprights, and a notched lower member connected with theuprights, the notches being to frames.

2. A film-treatment cage comprising uprights, means connecting theuprights at each end to each other, foldable notched upper memberssupported by the uprights, and a foldable notched lower member connectedat its ends with the uprights, the notches being adapted to engagefilmho-lding frames.

3. In a film-treatment cage, a rack adapted to be inserted in a tank,the rack being provided with means adapted to co-operate withfilm-holding frames to detachably and separately suspend the frames inthe rack, the rack also being provided with means adapted to co-operatewith the frames to prevent swingin of said frames.
